How Much Radiation From Dental X Rays

Spending 3 Days In Atlanta

Are Dental X-rays Safe?

Atlanta offers a wide range of attractions that might entice you to visit for the weekend. However, spend a mere three days there, and you will receive the same amount of radiation exposure as you would receive from your annual dental X-rays.1 Would you rather go to Denver? You only get to stay two days in Denver before you have exceeded your annual equivalent you would receive from dental X-rays.1

Lets discuss your mode of transportation to get to your destination. If you are planning to fly, depending on your departure location, that is going to add another year worth of radiation exposure equivalent to, or exceeding, the amount you would receive from dental X-rays before you even reach your destination.

Although traveling and vacationing is much more fun than getting dental X-rays, when it comes to radiation exposure, it is safer to visit the dentist rather than going on that trip.

Faqs For Health Professionals

» Who should I ask for detailed information regarding doses?

» What is meant by radiation dose of X rays?

Radiation dose is a measure of how much energy is absorbed when something or someone is exposed to X-rays. This is important because it is this absorption of energy that can cause damage to a person. Different quantities are used to express dose.

» Which quantity is used in practice to relate radiation dose to risk?

A commonly used quantity to express the dose to a person is effective dose, which takes into account the dose to different organs/tissues which are exposed . Effective dose is related to the risk for stochastic effects . Effective dose and its associated risk should not be applied to individuals, but can be used to compare between modalities, techniques and other sources of exposure . Non-stochastic effects (tissue reactions / deterministic effects may also occur at organ dose levels above a specific threshold.

» Which quantities are used to measure the dose from dental X ray equipment?

Since the effective dose cannot be measures, in practice, other dose quantities that are directly measurable are used for the purpose of optimization, dose monitoring, and quality assurance. They are specific to a certain imaging modality.

The measurable quantity is the entrance surface air kerma/dose. The unit of entrance surface kerma is the gray , but in dental radiology the dose levels are usually a small fraction of one gray – milligray , or even microgray .

What Are Dental X

Dental x-rays are used to make quick and painless images of your teeth and jaws. X-rays are invisible beams of energy, a form of radiation. The images are displayed on film or on the computer monitor after the x-rays pass through an area of the body and are absorbed differently depending on the density of the structures. Dense body parts such as bones and teeth absorb much of the x-rays and will show up as white areas on the resulting image, while less dense body parts such as nerves and muscles absorb less, showing up as shades of gray.

According To The American Nuclear Society This Is How Much Radiation You Expect From Common Activities:

620 mrem/year = the average level of radiation per person in the US

50000 mrem/year = the safe allowable dose for people that are exposed to radiation in their wok

1 mrem = two hours in a jet plane

7 mrem/year = from living in a brick house

10 mrem/year = cooking with natural gas

2 mrem/year = from sleeping next to someone else

36 mrem/year = from smoking one pack of cigarettes a day

42 mrem = breast mammogram per breast

700 mrem = abdominal x-ray

63 mrem/year = living in the Colorado Plateau area

0.5 mrem = one dental x-ray

The amount of radiation that a patient receives during dental x-rays is very small when compared to other sources of radiation in everyday life. In addition, our office uses modern digital x-rays. The amount of radiation received from a digital x-ray can decrease up to another 80%. That means while a standard x-ray gives off 0.5 mrem, a digital x-ray can give off as little as 0.1 mrem.

While digital x-rays do emit a very small amount of radiation, it is clear that the benefits greatly outweigh any minimal risks.

When Are Dental X

X-rays are often part of a yearly checkup and used to determine the overall health of teeth and gums. There are several types of x-rays used in specific scenarios.

  • Bitewing x-rays are taken to check for cavities between teeth.
  • A panoramic x-ray manages to get all the upper and lower teeth and large portions of the jaws in one picture. They are often taken to see how wisdom teeth are positioned, but can also be used to spot abnormalities in the jaw and neck area.
  • Periapical x-rays show a few complete teeth, their roots, and the jawbone in a certain area of the mouth.

Why Does The Dentist Use Different Types Of X

How to Read Dental X-Rays

Various types of x-rays are used by your dentist for very specific purposes. A combination of x-rays may be necessary depending on the treatment plan outlined by your dental team. Some of the x-rays your team may suggest include:

Bite-wing X-rays Bite-wings are the most commonly used x-ray during an initial exam and in subsequent check-ups. These highlight the crowns of the back teeth. Dentists take one or two bite-wing x-rays on each side of the mouth. Each x-ray shows the upper and lower molars and bicuspids

Periapical X-rays These x-rays focus on only one or two teeth at a time. A periapical x-ray looks similar to a bite-wing x-ray, but it shows the entire length of each tooth, from crown to root.

Extraoral X-raysExtraoral x-rays are made outside the mouth. These are considered big picture x-rays because they not only show the teeth, they also provide information on the jaw and skull and are often necessary for the effective treatment of TMD/TMJ.

Panoramic X-raysThis x-ray captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues and requires a special machine. The benefit of this type of x-ray is that it eliminates the need for multiple x-rays.

How Often Do You Need An X

How often dental x-rays should be taken depends on a patients oral health condition, age, risk for disease and any signs and symptoms of oral disease. The American Dental Associations long-standing position is that dentists should order dental x-rays for patients only when necessary for diagnosis and treatment.

And, of course, your dentist should be following the procedures recommended by the ADA to minimize radiation exposure. This includes the use of abdominal shielding . Also, the ADA recommends that dentists use E or F speed film for traditional x-rays, the two fastest film speeds available which lessen the amount of radiation needed for a good picture, or that they use digital x -rays.

If you have questions about the necessity for an x-ray ordered by your dental team, talk with them about why they feel the x-ray is needed. In the final analysis, you and your dentist must weigh the benefits of having an x-ray against the risk of minimal radiation exposure.

Who Should Not Get X

Pregnant women. If you are pregnant, you should avoid X-rays until after birth. This is to protect the health of the foetus, which is much more susceptible to radiation problems than grown adults.

The speed at which a foetus changes at the cellular and DNA level makes X-rays particularly dangerous. You should have regular dental check-ups during pregnancy. Just make sure your Ria Family Dental dentist knows about your condition.

Children. This is an arguable one. Theres no such thing as a completely safe exposure level, and radiation is cumulative over your lifetime.

Children may be vulnerable since theyre small, and their cells are dividing rapidly. Discuss this with your dentist.

Naturally Occurring Background Radiation

We are exposed to natural sources of radiation all the time. According to recent estimates, the average person in the U.S. receives an effective dose of about 3 mSv per year from natural radiation, which includes cosmic radiation from outer space. These natural “background doses” vary according to where you live.

People living at high altitudes such as Colorado or New Mexico receive about 1.5 mSv more per year than those living near sea level. A coast-to-coast round-trip airline flight is about 0.03 mSv due to exposure to cosmic rays. The largest source of background radiation comes from radon gas in our homes . Like other sources of background radiation, the amount of radon exposure varies widely depending on where you live.

To put it simply, the amount of radiation from one adult chest x-ray is about the same as 10 days of natural background radiation that we are all exposed to as part of our daily living.

Comparison Of Medical Dental And Natural Radiation Levels

Orland Park Dentist

When you visit with your oral surgeon in Chicago, chances are that you will need to have at least one advanced x-ray as part of your examination. Whether you are having your wisdom teeth evaluated or you are interested in dental implants, sophisticated x-rays are necessary and will provide a wealth of information about your anatomy.

If you have ever wondered about the effect of dental x-rays on your body or the amount of radiation that is produced with each press of the button, then you are not alone. Traditionally, dental x-ray technology has been exceptionally safe. With ultra-sensitive x-ray film and highly focused x-ray beams, the exposure to the dental patient was minimal.

Today, with the use of digital x-ray imaging, the radiation dose is even lower than ever before. In fact, compared to other sources of natural and medical radiation, dental imaging generally produces a significantly lower dose.

Since radiation is naturally created in the environment, it is helpful to compare medical and dental radiation exposure to a day in the sun. In the course of normal daily activities, you can expect to accumulate a certain amount of radiation. For instance, on a flight from Los Angeles to London, the estimated radiation dose is equal to approximately 10 days of natural radiation exposure.

A more thorough comparison between real radiation exposure values in milliseiverts can be found below in the accompanying tables labeled 1-3.

How Much Radiation Do I Get From A Dental X

If youve ever wondered why your dentist draped you in a lead apron and all of their staff step out of the room each time you need a dental X-ray, its normal to have some concern about the safety of the procedure.

Fortunately, getting dental X-rays today is extremely safeand the only reason why your dental team stays far away, is because of the risk of gradual exposure that accumulates day after day throughout their career.

Otherwise, dental X-rays are usually nothing to be concerned about!

How Often Should Dental X

The type and frequency of dental x-rays depends on the patients needs which are determined based on the clinical exam and risk factors. If you are a new patient, dental x-rays may be requested to determine your oral health and to have a baseline to identify changes that may occur later.

How often dental x-rays should be taken depends on:

  • Age and stage of development
  • Present oral health and clinical findings
  • Risk for dental caries and periodontal disease
  • If you have any signs and/or symptoms of oral disease

Common Activities That Expose You To More Radiation Than Dental X

10 Common Activities That Expose You to More Radiation Than Dental X-Rays

Radiation is one of the scariest things in the world. While it won’t usually make you glow in the dark, it could cause a bunch of awful things to happen to your body.

Many patients try to wiggle their way out of their dentist appointments because they’re worried about the radiation their dental x-rays might expose them to.

The good news is that very low levels of radiation aren’t hazardous. Dental x-rays expose you to less radiation than some activities you perform each day. In nitty-gritty technical terms, standard set of 4 dental xrays for a routine check-up adds up to .005 mSev of radiation. An average day in the life of your average Joe the Plumber exposes you to almost .010 mSev of radiation from background sources, AKA the stuff around us.

So let’s take a look at 10 harmless and ordinary common activities that expose you to more radiation than dental x-rays.

1. Drinking Water

Radiation exists naturally in the environment. It’s a by-product of certain chemicals breaking down. It permeates the soil that water flows over.

Man-made sources are regulated by the Environmental Protection Agency. The allowed levels of radiation are equal to the amount of radiation an entire city absorbs each year.

You drink this water and absorb tiny amounts of radiation. This can expose you to more radiation than some of the more advanced x-ray techniques your dentist uses.

2. Breathing

3. Cooking on the Stove

How Can We Reduce The Radiation

How To Understand Your Dental X-rays (Dental Hygienist Explains)

To make sure the child exposure is reduced as much as possible the Image Gently campaign recommends dentists to:

  • Take x-rays based on the specific patient/ childs needs and not as a routine test
  • Use up to date equipment and techniques
  • Use thyroid collars and protective shields as needed for other body parts
  • Use child-size exposure times
  • Take Cone-Beam CT scans only when necessary

What Are The Health Risks Associated With Dental X

There is no evidence that dental x-rays are harmful if administered on an occasional basis. Most dentists agree that for healthy patients on a maintenance program and not looking for a specific treatment, x-rays every one or two years is appropriate. However, if procedures, such as extraction or root canal, are considered, additional x-rays may be required.

Be sure to wear the protective gear offered and follow the hygienist or dentists instructions.

When administered with care, x-rays are an important tool for the delivery of dental healthcare. Follow your dentists advice regarding frequency and try not to worry about radiation. The minor risk is worth it for the information that can be added to your dental chart.

Ceramic Floor Tiles And Granite Countertops

Natural radionuclides in building materials may cause both external exposure, caused by their direct gamma radiation, and internal exposure, from radon gas. The gamma radiation arising from the walls, floors, and ceilings radon and thoron, and their progeny, are major sources of radiation exposures.

The worldwide average indoor effective dose due to gamma rays from building materials is estimated to be about 0.4 m Sv per year, or 40 mrem, the equivalent of 80 dental X-rays. As individuals spend more than 80% of their time indoors, the internal and external radiation exposure from building materials creates prolonged exposure situations.2 If you have ceramic tile or granite in your home, you are receiving more annual radiation exponentially from being indoors than you will receive from getting your annual dental X-rays.

How Much Radiation Is In An X

When X-rays were first introduced, dentists and other professional did not understand the danger of repeated radiation exposure, and proper safety features and procedures had not yet been developed.

However, as knowledge and technology have advanced, the amount of radiation used and possible patient exposure to it has decreased dramatically.

To put dental X-rays into perspective, lets compare them to other environmental sources of radiation.

For perspective, a single digital dental X-ray has 0.1mrem of radiation, and a set of 4 bitewings has 0.4mrem.

Compare that to:

  • Natural radiation from soil: 35mrem per year
  • Smoking cigarettes: 1,300mrem per year
  • Transcontinental flight: 2-4mrem
  • Drinking water: 5mrem per year
  • Using natural gas for heating and cooking: 9mrem per year

Its pretty clear how low the level of radiation is, in a dental X-ray.

One aeroplane flight across the country gives you more radiation exposure than X-rays and eating ten bananas exposes you to as much radiation as one X-ray!

Basically, while dental X-rays expose you to some radiation, the benefits of having them performed outweigh the risks.

Many dental problems are invisible to the naked eye, and X-rays let your dentist discover a range of problems in tooth enamel, gums, and tooth roots.
